Police found the victim’s body shortly after 6:40 p.m. Saturday at a residence in the 7600 block of Muleshoe Lane on the Southwest Side. Montez-Deoca had suffered a gunshot wound to the chest and hand, as well as a cut on his neck. He was lying in a pool of his own blood, the affidavit said.

Police also found a 9mm shell casing in the bathroom of the residence.

Messick allegedly told police in an interview that she stood in the bathroom of the residence and shot Montez-Deoca as he was standing in the hallway following an argument.

She said she was thinking “What an a**hole. What a jerk,” when she allegedly shot him, according to the arrest affidavit. She also allegedly told police she cut his neck with a knife because she wasn’t sure if he was dead or not when she shot him.
